Description
The study of high redshift galaxies is crucial for understanding the
reionization process, the formation and evolution of galaxies, and the
large-scale structure in the Universe. The main goal of this project was
to obtain an ultra-deep image taken with a narrow-band filter (FWHM =
11nm and central wavelength λ_{c} = 1.254 μm), designed by the
ALBA team, and installed in the CIRCE nIR camera for GTC, with the aim
of detecting LAEs (Luminous Lyman-α Emitters) at z = 9.3 by the
flux excess due to their Lyα emission. In this sense, this project
would allow to support or reject the double reionization scenario
predicted by the AMIGA model (Salvador-Solè 2015). The ultra-deep
image has been obtained within the Extended Groth Strip (EGS) field,
reaching a limiting AB magnitude ˜ 22 in the ALBA narrow-band
filter. With this depth we could not detect any candidate for LAE at
high redshift. In addition, we have performed a scientific analysis of
some properties of the identified galaxies, gathering the available
ancillary information of these objects from the 3D-HST and CANDELS
surveys.
